OIGEN's Summer Cast Iron Teapot: A New Way to Enjoy Chilled Sake on Warm Nights

When most people think of a Japanese cast iron teapot, they imagine a quiet afternoon, freshly brewed green tea, and the comforting warmth of a traditional tea ritual.

But this summer, OIGEN invites you to experience something different.

Instead of pouring hot tea, imagine filling a beautifully chilled cast iron teapot with crisp Japanese sake. As the evening cools and conversation slows, the teapot becomes more than a tea vessel—it becomes the centerpiece of a memorable summer table.

A Cast Iron Teapot, Reimagined for Summer

At the end of a hot summer day, reach for a chilled cast iron teapot.

Toku, toku...

The gentle sound of cold sake filling a glass is surprisingly satisfying.

A teapot serving chilled sake?

That unexpected combination is exactly what makes the experience so enjoyable.

Thanks to the natural thermal properties of cast iron, the teapot helps keep your drink refreshingly cool, making it an elegant alternative to a traditional sake carafe.

The 2026 Summer Limited Edition: Inspired by the Japanese Night Sky

For the 2026 Summer Collection, OIGEN introduces three exclusive seasonal colors inspired by the beauty of Japanese summer evenings:

• Yoi (宵) – Early evening, when daylight quietly fades.
• Sayo (小夜) – The peaceful stillness of late evening.
• Shinyo (深宵) – The deepest hours of the night beneath a sky full of stars.

Among them, Shinyo is perhaps the most captivating.

Its finish is created by layering black, silver, and black over a dark base, producing remarkable depth that evokes countless stars shimmering against the midnight sky. Depending on the light, the surface subtly changes its appearance, making every teapot feel alive.

Traditional Nambu Tekki Craftsmanship

Handcrafted in Iwate Prefecture, Japan, each teapot showcases the timeless beauty of Nambu Tekki craftsmanship.

The finely textured cast iron surface is paired with clean horizontal lines, creating a modern interpretation of a centuries-old tradition.

The accompanying cast iron trivet features the classic Arare (hailstone) pattern, reimagined by Japanese metal artist Shin Hirose. More than just an elegant accessory, it protects your table from heat and moisture while perfectly complementing the teapot's minimalist design.

Together, the set blends effortlessly into both traditional Japanese interiors and contemporary dining spaces.

Beautiful, Durable, and Easy to Care For

Unlike ceramic teapots, cast iron offers exceptional durability.

The interior is coated with enamel, preventing rust while making cleaning simple with warm water, mild detergent, and a soft sponge.

Originally designed for tea, the teapot is also ideal for:

• Chilled Japanese sake
• Cold brew tea
• Herbal infusions
• Soup broth for ochazuke
• Iced specialty beverages

Its versatility makes it a piece you'll reach for throughout the year.

Note: This enamel-coated teapot is intended for serving beverages only and should not be used directly over heat or to boil water.

Cast Iron Doesn't Just Retain Heat—It Keeps Drinks Cool

Cast iron is famous for its excellent heat retention, but fewer people realize that it also performs remarkably well with cold beverages.

Simply remove the stainless steel tea strainer, chill the teapot beforehand, and pour in your favorite sake.

The cast iron body helps maintain a cool serving temperature longer, allowing you to enjoy each glass at a relaxed pace without rushing.

Sometimes, the best discoveries come from using a familiar object in an entirely new way.
